As applications become more demanding, Machine Tool Manufacturers require components that not only deliver precision but do so reliably over long production lifecycles. That is where proven systems make the difference. ## A Foundation of Proven Rotary Table Designs ABTech’s heavy-duty rotary tables (HDRTs) are known for their strength, stability, and ability to support demanding loads while maintaining precise rotational motion. These designs have demonstrated their value across decades of industrial use, providing the stiffness, load capacity, and durability required for demanding applications in manufacturing, inspection, and assembly systems. ABTech’s heavy-duty rotary table platforms have been performing in demanding applications for decades, long before customers began looking for alternatives to legacy AG Davis systems. Built on proven architectures and executed with modern engineering and manufacturing capabilities, these tables deliver industry leading performance and reliability. The result is a rotary table platform capable of delivering reliable performance at an incredibly high level of precision. ## Engineering that Improves Proven Designs At ABTech, proven design does not mean static design. Our engineering team continually evaluates how systems can be improved, whether through refined tolerances, optimized materials, or improved manufacturing methods. When necessary, we are willing to re-machine, re-engineer, or redesign a product to ensure it performs exactly as required and meets customers’ expectations. That same engineering discipline underpins every project we undertake. Careful analysis, testing, and refinement ensure that performance and reliability are the guiding principles of everything we produce. ## Our Process Explained by Our Engineering Team *“Every new inquiry brings someone else’s challenge that quickly becomes our passion through the lifecycle of the project. Collaborating towards a solution with the goal of pairing decades of experience and a library of design history with our manufacturing strengths is where our engineering focus is.” *  — Joseph Kelly, Engineering Manager ## Investing in Capability to Build Bigger Systems Supporting larger and more robust motion systems requires more than engineering expertise. It requires the infrastructure to manufacture them. ABTech has made significant investments in larger machining centers, expanded capacity on our shop floor, and a growing team of engineers and machinists. These investments ensure that we manufacture increasingly large and complex motion systems while maintaining the high standards of precision for which ABTech is known. This expanded capability supports not only our heavy-duty rotary tables and large-scale precision spindles, but also the integrated motion components built for demanding OEM production environments. ## Built Bigger, with Purpose ABTech’s focus today is clear: build robust motion systems designed for real-world production. From ultra-precision air-bearing spindles to heavy-duty rotary tables and integrated engine assembly systems, our goal is the same: to deliver motion solutions that combine precision, durability, and long-term reliability. As OEM systems become larger and more complex, the processes, technology, and commitment to precision behind them also grow stronger.   [**Contact us today**](https://info.abtechmfg.com/contact)** to start the conversation.** ## Can’t Find What You’re Looking For?
